      High-speed Hair Dryers
      Leveraging the full-chain synergy of its IDM model, crmicro provides customers with complete solutions for high-reliability brushless motor control, and main controllers, as well as semiconductor devices，which helps customers develop efficient, low-noise, durable, smart and convenient daily small appliances.
      Solution Overview
      Targeting the control solution for high-speed brushless hair dryers, focusing on variable-frequency drive and control of the high-speed brushless motor, auxiliary system power supply, and isolated signal sampling. Using half-bridge IPM power modules/SJ MOSFETs, dedicated motor MCUs with voltage regulation, high-precision op-amps, infrared thermopile, and high-reliability optocouplers, it offers a turnkey solution that achieves fine-grained variable-frequency control of high-speed motors, improving noise level and long-duration continuous operating stability.
      Solution Advantages
      • Energy saving & high efficiency lead to low operating cost
      • Meets the computing power requirements for a 4-pole motor at a mechanical speed of 110,000 RPM.
      • Precise algorithm control delivers strong system stability
      • Not sensitive to motor parameter variations, adapting to complex operating conditions
      • Strong anti-interference capability and support for small electrolytic capacitors
